Sure, let's go through each problem step-by-step.

15. Evaluating $f(x)$ from the Graph

For $f(x)$:

a) $f(-3)$: Find the y-value when $x = -3$.
b) $f(5)$: Find the y-value when $x = 5$.
c) $f(0)$: Find the y-value when $x = 0$.

16. Evaluating $h(x)$ from the Graph

For $h(x)$:

a) $h(3)$: Find the y-value when $x = 3$.
b) $h(-1)$: Find the y-value when $x = -1$.
c) $h(-2)$: Find the y-value when $x = -2$.

17. Evaluating from Tables

Using the provided tables:

a) $h(2)$: Look for $x = 2$ in the $h(x)$ table.
b) $g(4)$: Look for $x = 4$ in the $g(x)$ table.
c) $f(0)$: Look for $x = 0$ in the $f(x)$ table.
d) $f(2)$: Look for $x = 2$ in the $f(x)$ table.
e) $h(1)$: Look for $x = 1$ in the $h(x)$ table.
f) $g(0)$: Look for $x = 0$ in the $g(x)$ table.

18. Finding the Equation

For each set of values, determine the equation by finding the pattern or relationship. You can use methods like finding a common difference for linear relationships or ratios for exponential relationships in the data.
